While the poster at Paradoxoff is slagging this "Elektronika MK-152" programable calculator—and it is very humble, with only half a meg of memory, membrane keys, and no power supply—I find its sturdy Russian construction and no-fuss design appealing. Of course, I don't have to use it, only admire it from afar.
But as one commentor noted:
The programming language of this device is very easy. There are many problems for non-programmers that should be solved. How much does it spend for engeneer to write program that realize his new function, if he doesn’t programming languages? In C++ it spends more than half of day. In this device it spends less than 15 mins. And about memory for example: a program to calculate square root takes 24 bytes only.
Then again, this thing is going for over $150 in Russia, so expecting a few more modern features is not unreasonable.
